Update: Matt Every's putting stroke deserted him a bit in the final round of the Sopny Open. He needed 31 putts in shooting a final-round 72 (2-over) and tied for sixth at 10-under, three shots behind winner Johnson Wagner.

The jokes have been rampant about Matt Every's putter this week at the Sony Open in Hawaii.

A shoe box on a stick. A copy of the Rules of Golf on a stick. The Black Box.

And on and on.

Truth be told, the putter is the creation of David Kargetta of Daytona Beach, which is Every's home town. Kargetta, of Daytona Beach Shores, said Every and he made contact through "mutual friends," and was not very forthcoming about production and plans for retail sales, rare for an independent equipment designer.

"We're not ready to talk specifics about it," Kargetta told me Sunday. "Whatever Matt does this week should be about Matt, not about what he's doing with the putter."

Kargetta said he received USGA approval for the putter last February. He would not reveal the weight and dimensions of the huge, black putter head, nor what he considered the main benefits to a player rolling the ball with such a large implement attached to a putter shaft.

There is no web site. Kargetta does not have a retail shop. No one can buy it -- yet. He said he was planning to put the putter on sale in March but admitted it might be sooner, based on the attention Every is getting from leading the Sony Open for most of the tournament so far.

Indeed, Kargetta was extremely reluctant to talk about the putter at all.

Every has taken 27, 25 and 30 putts in the first three rounds. The former University of Florida All-American showed me the putter at the Henry Tuten Gator Bowl Pro-Am in Hawaii, where he used it to help his team finish second. He wasn't specific in how it's helping him -- he only knows that it does.

P.S. The Magnolia Point Country Club apparently is the only shop in town that has some of the Black Hawks in stock and are selling them in the pro shop. Call (904) 269-9276 to check on their supply.
